MARINE BUOY.

Specification of Letters Patent.

Patented Jan. s, 1918.

Application filed September 7, 1917. Serial No. 190,152.

To all whom it may concern:

Be it known that I, Fnnnnmo WM. ERICKSON, residing at New York, in the county of New York and State of New York, have invented certain Improvements in Marine Buoys, of which the following is a specification.

This invention concerns marine buoys located in canals, rivers and bays to indicate in waterways channels for the passage of water craft and places of danger to be avoided; and also relates to a novel construction of such buoys in that I make them of reinforced plastic material, as concrete, instead of wood, and cast or wrought-iron. The buoy is made in sections, which are secured to each other and hermetically sealed, and are preferably made in molds; the reinforcing material is usually of iron or steel rods bent into rings or a spiral and placed in the mold and the concrete forced and rammed around them and then allowed to dry. All rings, bolts, etc., needed in the complete structure are placed in position in the mold to be embedded and when the concrete is dry are adapted for their several uses. When assembled and the several sections and members are in proper shape, the outward surfaces are covered with a suitable waterproofing substance to protect the same from penetrating moisture and also from ordinary abrasion.

I will now proceed to describe in detail a preferred construction and indicate the invention in appended claims.

In the drawing which forms a part of and illustrates this specification, the figure is a side view partly in section of the marine buoy constituting my invention.

Referring to the drawing, the construction shown consists of two shells or members of suitable thickness. The lower A is to be partly immersed and is of concrete reinforced With metal rings or spiral bars or wire V, and has a rounded lower end a, with straight upward sides, which enlarge to the part b, which terminates in the heavy end 0, provided with the outward lip f, and the channel 03 in which enters the edge 6, forming the terminal of the sloping to of the cover of the member B, between whlch lip f and edge e is the seal 9 of hard pitch, asphalt, or the like. This will make a good water-tight joint, and enable the parts to be separated and repaired if necessary.

Metal gromets h are cast in lugs a: in the concrete at the intermediate level and one gromet IL in the lug Z at the lower end of the section A, for the attachment of ropes or cables for eounterweights and anchoring purposes, to take care of abrasion and friction.

A wood buffer ring 7" is located along the submersion or water line 10, having a protccting band 7', and secured to the concrete body by anchor bolts k and intended to take care of collisions and to be renewable.

The top of the concrete cover or member B is of suitable thickness and fitted with an iron flange a threaded to receive an iron pipe mast m, the upper end of which is intended to hold a lantern L of the regulation type for oil, gas or electricity.

A bilge water pipe t is cast into the concrete cover and has a water-tight screw cap 8 through which a suction pipe may be in serted for bailing of the buoy, if necessary.

The embedded reinforcing metal bars or wires V may be in the form of a spiral, rings, or any preferred form or shape, and are placed in a mold, with the other metal parts to be inclosed, gromets, pipes, etc, and the concrete is packed around the same and allowed to become hard, in a well known manner, when the parts are ready as a whole for use. As the constituents of concrete and its manipulation are matters of common knowledge, no description thereof is necessary.

I claim as my invention 1. A marine buoy made of reinforced concrete sections or members hermetically sealed to each other. the exterior surface of which is waterproofed, having a buffer ring at the water line, provided with signaling means to indicate its presence and position, and means for attaching anchoring ropes or cables.

A hollow marine buoy consisting of circumferentially divided reinforced concrete sections or members, hermetically sealed to each other, an extension from the upper portion provided with signal means as a lantern, a protective buffer ring at the water line, and means for attaching anchoring ropes or cables.

3. A hollow marine buoy consisting of upper and lower members hermetically sealed to each other, each member made of reinforced concrete, the upper portion having an upward extension bearing upon its end signal means as a lantern. a buffer ring at the water line, and means for securing anchoring ropes or cables.

4. A hollow marine buoy consisting of end of the upper member and be sealed thereto, the lower member having means to which anchoring ropes and cables may be attached, the upper member provided with an upright mast or rod bearing on its end signal means.

5. A hollow marine buoy consisting of two shells or members made of concrete re inforcedwith embedded metal-bars or wires, the lower member being the water immersed portion and surrounded at the water line with a protective bandorring and having thereto, the lower member having means to which anchorin ropes and cables may be attached, the upper member provided with an upright mastor rod bearing on its end signal means, with means in said upper memher for permitting the withdrawal of bilge water from the buoy.

In testimony whereof, I have signed my name to this SPGClfiCHiJlUZl in the presence of two subscribing witnesses, this 4th day of September 1917. I v
